Colleges have increasingly turned to predictive analytics to target at-risk students for additional support. Most of the predictive analytic applications in higher education are proprietary, with private companies offering little transparency about their underlying models. We address this lack of transparency by systematically comparing two…

The prediction that differences in incomes of high school and college graduates will not change is tested by applying standard statistical procedures to data describing actual income differences. Data from the United States Bureau of the Census describe annual incomes of men twenty-five years old and older during 1956-75. Report 1 displays results…

Published reports and papers pertaining to the validity of measures commonly used at college entrance are reviewed and summarized in this report. These measures consist of various types of academic quantitative indices used to describe the high school record and various types of academic tests. The data are categorized by sex and ethnic…

This document presents the 1995-97 Biennial Washington state education budget forecasts for K-12. A total of 18 tables in the main body of the report present the data which includes: average annual K-12 full time enrollment (FTE) overall and by grade groupings; comparison of average annual FTE to October FTE; October headcount enrollment; running…

Membership projections are presented for South Carolina schools (excluding South Carolina Youth Services, Palmetto Unified, Felton Laboratory School, and South Carolina School for the Deaf and Blind) for the period 1991 through 1996. Membership projections are calculated annually using average daily membership (ADM) (enrollment) in conjunction…

Statistical projections for elementary and secondary schools and institutions of higher education are provided at the national and state levels through the year 2001. National projection tables cover enrollment, high school graduates, earned degrees conferred, classroom teachers, and expenditures of public elementary and secondary schools.…

Bayesian methods for estimating dose response curves in quantal bioassay are studied. A linearized multi-stage model is assumed for the shape of the curves. A Gibbs sampling approach with data augmentation is employed to compute the Bayes estimates. In addition, estimation of the "relative additional risk" and the "risk specific…

This document provides tables and figures of current demographic data for the state, counties, cities, and towns of Washington. The report is divided into two main sections: (1) "State, County, City Populations"; and (2) "Selected Estimates and Information". Section 1 presents such data as: population change and net migration…

Many factors influence the grades students earn. Without the intervention of institutional forces, it is reasonable to suspect that the mean semester index of successful students will remain constant with the passage of time. If, on the other hand, institutional variables exist that influence grading standards, then it is reasonable to suspect…

The problem of forecasting monthly demands for library network services is considered in terms of using forecasts as inputs to policy analysis models, and in terms of using forecasts to aid in the making of budgeting and staffing decisions. Box-Jenkins time-series methodology, adaptive filtering, and regression approaches are examined and compared…

This report contains the first projections produced by the federal government of the Spanish-origin population by age, sex, and race for the years 1983 to 2080. These national projections, based on 1982 population estimates, show what the future Spanish-origin population would be under various assumptions about fertility, mortality, and net…

Each year the National Center for Education Statistics (NCES) publishes a pocket summary of their "Projections of Education Statistics." This summary reviews data on U.S. education from 1980-81 and provides predictions of educational data until 2002-03. Included are tables summarizing population trends and tables of elementary school and…

In 1989, Cochise College (CC) conducted a study to determine if a positive relationship existed between grade placement scores on the Nelson-Denny or Nelson reading comprehension examination and academic performance. The study population consisted of new or first-time CC students who were tested after May 1989. Placement scores for students who…

In 1979, the Western Interstate Commission for Higher Education (WICHE) began its high school graduates by state projections. The three editions issued since that time have been widely used. This report provides an analysis of the accuracy of the WICHE's projections and an examination of the cohort survival method used to generate the projections.…

Three tables are provided to aid in the clinical interpretation of factor scores for the Wechsler Adult Intelligence Scale-Revised (WAIS-R; 1981). The factor structure of the WAIS-R has proven to be robust across samples, tests, time, statistical analyses, measurement scales, and distortions of the distribution. Information necessary to make…
